If you were near downtown between 3 and 4 p.m. Saturday, you might’ve seen it: An arms-to-back line of 50 or so people crossing streets, watching their feet and getting all kinds of looks from confused bystanders.

Most of the those involved were on the mailing list for Emerald City Improv, the group that occasionally stages scenes of streetside silliness. A few saw the procession and joined in.

“I think we really made their day,” co-organizer Luke Greenway wrote in an e-mail. “And any time we do that, it’s mission accomplished.”

Co-organizer Kelsey Wildstone managed to get a handshake from a man on the sidelines.

“‘Thank-you. Thank-you for bringing good energy to this city.’ That had me in shock for a minute,” Wildstone wrote. “It was a really good moment for me.”
